It's fine to reach for chocolate from time to time (remember, dark is best) — but just keep it to small amounts and try not to emphasise consumption either.
Research suggests that family meals play an important role in promoting healthy dietary intake in children, especially as they get older. Research has shown teenagers who eat meals with their family consume more fruit and vegetables, are less inclined to have extreme weight control behaviours, have better psychological health and less risk of obesity.
Children need to know that foods with a low nutritional content are not "every day" foods. So items like soft drink, chips, pastries, lollies, cakes and biscuits are "sometimes" foods and should only be consumed on special occasions. It's all about balance. Be careful with this strategy however, because being too restrictive can make a "sometimes" food even more desirable.
By enjoying lots of healthy foods (fruit, vegetables, wholegrains, low-fat dairy, soy, nuts, seeds and legumes) ourselves, we can teach our children how to put good food into their growing bodies and that they'll feel all the better for it.
